Strongly nonlinear waves in a chain of Teflon beads [PDF]
, 2005 One dimensional "sonic vacuum" type phononic crystals were assembled from a chain of Teflon spheres with different diameters in a Teflon holder. It was demonstrated for the first time that this polymer-based "sonic vacuum", with exceptionally low elastic

Highly nonlinear solitary waves in chains of ellipsoidal particles [PDF]
, 2011 We study the dynamic response of a one-dimensional chain of ellipsoidal particles excited by a single compressive impulse. We detail the Hertzian contact theory describing the interaction between two ellipsoidal particles under compression, and use it to
